The stand cannot" With this construction themanufacturer asordinarily be assembled and properly positioned semblesthe stand and rear axle assembly of the on the bicycle all ready to usewhen shipped in bicycle in exact condition for use before it leaves thecrate, as the wide foot portion 3 of the stand the factory. In cratingthe bicycle the legs 1 is wider than the crate commonly used for the and2 of the stand are sprung together with bicycle. So the common practiceis to ship the parts 3 and 3" overlapping and nested and held stand as aseparate part and merely put it in the in such position by leaf spring'7 with its pin 10 crate, for the boy to put on the bicycle after he andhead 9 passing through hole 8 of part 3 and uncrates it. under shoulders11. In this position (see Fig. 2) I have found out that in manyinstances a boy legs 1 and 2, due to their normally diverging shape andtheir attachment at the rear axle, have a strong tendency to springapart. But they are held together at approximately the width of thebicycle and its crate, by engagement of pin 10 passed through hole 8 andunder shoulder 11, all in' the right position for crating the bicycle,as shown by the dotted line position in Fig. l.

When the bicycleis uncrated all the boy has to do is to push parts 3'and 3 slightly together to disengage pin 10 and its head 9 from part 3".

Then legs 1 and 2 will spring to their normal diverging position. Pinhead 12 and its head 13 will now be pressed into hole 8 andthe pin will:move to slot 11. In this position parts 3' and 3 of foot 3 will be inalignment, their ends will be" abutting, and the parts will be heldthere, as in Figs. 1 and 5, for bicycle stand use. The leaf spring 7will overlap the out parts 3' and 3" of foot piece 3, and the whole willbe braced for permanent use in this position.

and his customers;

I claimi" 7 7 I. A' bicycle stand comprising in combination twodiverging leg members adapted to have their inner ends attachedto'oppositesides of" the rear fork, an inturned foot member at the outerend of each leg member in the form of a bend from the leg member, eachleg and its foot member being made integral from a single piece ofmetal, said foot members being normally adapted to lie in aligned toe totoe relation when the leg members are in diverging position and attachedto the bicycle, cooperating member-the toot members to hold themnormally and rigidly in, sakl relation, said means being movable topermit the foot members to overlap and bring the leg members closer tothe side of a bicycle whereby the latter may be assembled with the standat the factory and conveniently shipped in assembled relation.

2. A bicycle stand including a stirrup-shaped metal bar of channelcross-section, the foot portion being transversely split to permit thehalves to overlap and nest in the channel-shaped section, and a; bracefor the foot portion at all times overlying the overlapping portions andin position: to function when the halves are aligned at said split so astohold the foot portion rigidly as asingle piece, all for the purposedescribed.

3. In a bicycle standof the kind described, the

combination of aground bearing cross supportv made of two metal partseach of channel crosssection; and a long leaf spring attached'to andadaptedto lie in one channel part and overlie the other, said spring andthe other channel part having a cooperating pin and slot and hole meansfor attaching the two parts intwo' posi-,

tions, one for the parts to overlap and the other for them to be held inrigid aligned position, all for the purpose described.
